PSR2 doesn't actually say that a multi-line IF condition needs to be indented, but PHPStorm is obviously putting in 1 indent because your lines are inside an IF condition and 1 additional indent because your lines are inside a multi-line function call.

I have no idea if PHPStorm would agree with that, but I think it might given the indent rules it appears to have.

You can also put the && at the end of the first line instead of at the start of the second. The code I posted above is just what the PEAR coding standard uses, but PSR2 doesn't define any rules for this.
